Self-Healing Predictive Control of Battery System in Naval Power System With Pulsed Power Loads

This article presents a model predictive self-healing control (MPSC) scheme for battery system interfaced dual active bridge (DAB) converter in navy ship power (NSPS) with pulsed loads (PPLs). The voltage and frequency of NSPS are vulnerable to PPLs energization. A properly controlled fast dynamic response can mitigate this vulnerability. Model (MPC) is potential solution the DAB achieve disturbances imposed by PPLs. However, conventional MPC framework suffers from current prediction error due pulsating AC-link inductor's profile converter. proposes loop that utilizes feasible range transfer conjunction profile. proposed method validate autonomously correct predicted phase shift system. on prevents collapse hybrid AC/DC particularly during PPL stability studied based Lyapunov analysis. theoretical concepts validated several case studies implemented hardware-in-the-loop (HIL) testbed NSPS. demonstrate regulation MPSC performance compared proportional-integral (PI)
